REVO C13428 (Festival)

Genre: Enclosed Vertical Tubular Fluorescent Lantern

After the invention of the tubular fluorescent lamp in 1937 by GE of America, its application to street lighting was immediately recognised, but all development was delayed by the Second World War. After hostilities ceased, trial installations using tubular fluorescent lamps were installed in Dublin (using trough reflectors) and a year later in Rugby and London (using scientifically designed lanterns).

The advantages of fluorescent tubes were immediately apparent. The fluorescent tube was ideally suited for road lighting, casting a wide beam across the road surface and was relatively unaffected by wet conditions (which lead to streaks from more compact light sources). It's non-dazzling white light (due to the low surface brightness of the tube itself) made it an ideal solution for the lighting of high streets, promenades and civic areas, with smaller units used for residential streets. The only problem was the size of the tubes, which in turn lead to large lanterns.

The first fluorescent lanterns were huge, bulky affairs, their size dictated by the bulb lengths, the enormous gear and the limitations of the raw materials of the late 1940s: the lanterns consisted of plate glass panels and metal frames. The optical system was also complex treating each lamp as individual source and concentrating its beam in one area using parabolic polished metal reflectors. Their large size, and equally large capital cost, made lighting authorities hesitant to use these lanterns.

Fluorescent's popularity increased as new aluminium alloys allowed lighter one-piece canopies to be cast, which in turn supported new plastic moulded bowls. The optical systems changed again with all the tubes contributing to the whole: a primary system of lightweight plastic refractors directed the flux onto the road surface and fashioned the main beams; whilst a secondary system (comprising of white over-reflector) directed light above the horizontal back to the refractor plates.

Therefore the lanterns became simpler to manufacture and, in turn, their purchase price decreased. They were still an expensive option, but authorities could justify their use due to their excellent white light (as compared to the more "artificial" coloured mercury and sodium lanterns). Fluorescent lighting was especially popular in new town developments and many manufacturers pointed this out in advertisements.

The lantern's large size was still a problem and manufacturers took a tip from European practise and angled the lantern slightly to disguise its length. Whilst this threw the light further across the road, it was usually done for cosmetic reasons alone.

The 1950s and 1960s were the age of the fluorescent lantern: it's white light seen as an energy efficient replacement for ageing tungsten and gas lighting. As gear sizes were gradually decreased, the manufacturers took advantage by streamlining the lanterns further. Optical systems became simpler until they eventually consisted of no more than the tubes themselves with a small over reflector.

The energy crisis of the 1970s prompted a rethink. The complex white light fluorescent lantern, usually burning multiple tubes, was seen as an expensive luxury: a unit burning two 40W bulbs could be replaced by a single low pressure sodium lantern burning a 35W bulb. The idea that orange light was unsuitable for residential areas and high streets was swept away by economic necessity. Therefore, as an energy saving measure, the tubular fluorescent lantern was gradually removed, to the extent that hardly any exist on public streets anymore.

The use of the tubular fluorescent lamp for street lighting was over. (Although the future looks bright for the compact fluorescent lamp but that's another story...)

The REVO Festival was a symbol of civic pride and post-war optimism. It was designed for the central streets of Birmingham in 1951 by its council as part of the festivities sounding the national-tonic The Festival of Britain. However, Birmingham’s council members weren’t being futuristic when designing their festival piece, as the REVO Festival had a strong classical design, opting for fluted column and carved patterned canopy and spigot decorations. (It most definitely wasn’t the ‘Skylon’).

Vertical fluorescent was always a poor choice for street lighting as vertical linear sources were ill-placed to through much light upon the road. Additionally the lantern had no optical control, the tall Perspex sleeve simply acting as a diffuser. However, the science of lighting wasn’t entirely ignored: Birmingham’s engineers hoped the indirect light from reflections of surrounding facades would light the immediate area; and the spread of light into the heavens was also desirable as it alleviated the dreaded ‘tunnel effect’ which was so unfashionable in the 1950s.

Therefore post-top vertical fluorescent were never the most popular of choices for Group ‘A’ lighting; although they found favour in historical town centres where the lights doubled up as both (poor) streetlights and building floodlights (as they washed the facades of buildings with a warm, ambient glow). They were also popular along sea fronts; the non-directional nature of the light providing a gentle illumination over the entire area. Additionally new towns chose more futuristic styled lanterns as a notable act of statement.

But it all cases, the choice of vertically mounted fluorescent post-tops was definitely a case of aesthetics over good street lighting practise.

The Festival continued into the 1960s, but its poor light control meant it had limited application, and it eventually disappeared from the catalogues. Most Festivals were removed in the 1970s and 1980s when the cost of multiple fluorescent lanterns became too high, and their poor street lighting characteristics finally counted against them.

Although its usage was limited, the REVO Festival was installed in several towns, managing to become popular with both sticky candy-floss seaside parades and snooty academic town centres. REVO even produced a modern version, with angled lines and a tapered bowl, obviously anxious that the Festival should have a slice of the new town action as well.

It’s design provided inspiration for a famous, architect-designed, limited edition. Sir. Albert Richardson, searching for ideas when asked to design a street light for the city streets of Cambridge, used the Festival as his prototype. The Festival leant its lines (and optics) to the Richardson Candle: a more austere, linear version of the Festival which toned down its classical leanings.

Ironically, a lantern which was designed for the forward looking Festival Of Britain is now seen as a classic in its own right. York conservationists lamented the loss of their historic street lights when the Duncombe Place REVO Festivals were removed; architect Ptomley Dean attempted to list the Park Crescent, London examples after a flurry of publicity through the Evening Standard (but their history became confused, as a Richardson connection couldn’t be proved, so English Heritage refused the listing).

Only a tiny number of Festivals now remain.


The column and lantern are unique and should be easy to identify. (Incidentally some lanterns were mounted on REVO Scopas concrete columns instead of the fluted cast iron, although all of these are probably gone). Whilst there’s nothing on the exterior of the lantern, REVO cast their name into the base of the lantern where the fluorescent tubes were originally fitted.

Optical System

In a word: none. The light is essentially totally uncontrolled, the Perspex tube acting as a giant diffuser, disguising the multiple light sources within, and scattering light in all directions.


All the gear was mounted on the central spine of the lantern. (However, the original lamps, mountings and gear have all been replaced in my example).

The REVO C13428 (Festival) In My Collection


This lantern was originally one of the eight which stood in Duncombe Place, York where it lit the approach to the York Minster.


The lantern comprises of a spun canopy, central spine, and large base casting which also incorporated a spigot. Four fluorescent tubes were originally housed in the lantern, a large Perspex sleeve acting as a diffuser to disguise the multiple light sources. Pictured is the knurled canopy screw which, when unscrewed, allows the canopy to be removed and then the Perspex sleeve to be lifted off.

The lantern has been fully restored and painted black, which was York’s colour of choice.

ladder bars

The ladder bars were custom made by York City Council and allowed hanging flower baskets and/or banners to be hung from the lanterns.


After over fifty years of service, the lantern is still in remarkably good condition. This is primarily due to most of the metalwork being made of aluminium.

Unfortunately the Perspex sleeve is starting to show signs of wear; the seam separated in the past, causing a two inch horizontal crack to appear near the top of the lantern. More worrying however is the ‘crazying’ which is starting to appear; a multitude of small interior cracks growing from several places on the sleeve. It isn’t known if this can be halted, or even repaired.

The original wiring, bulb holders and gear have all been removed with two Thorn Popular Packs now bolted to the central spine of the lantern. This has turned out to be both an elegant and cheap solution to replacing the lantern’s ageing electronics and no difference can be seen when the lantern is illuminated.

REVO C13428 (Festival): As Aquired

All of the Duncombe Place Festivals were saved and distributed amongst collectors. This is thanks to the kindness of the council (Ricky W. at City Of York Council), their contractors (Don A. at Amey) and the organisation of John Thompson.

Pictures of the full restoration process can be found here whilst a picture of the lantern’s in-situ can be found here.
